        "question": "What is the typical flight duration from Chicago to Washington?",
        "answer": "The flight from Chicago to Washington is about 600 miles, with a typical nonstop duration of 1 hour 50 minutes. The return flight to Chicago takes about 2 hours 5 minutes, making it 15 minutes longer.",
        "methodology": "Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.",

        "answer": "Ronald Reagan Washington National Airport (DCA) offers direct Metrorail access from Terminals B and C, making rail the fastest and most-used option for reaching downtown Washington, D.C. Taxis, ride-share services like Uber and Lyft, rental cars, car-sharing via Turo, and local buses (Metrobus and Fairfax Connector) are also available. The Metrorail station is elevated and connected to the concourse level, providing easy and affordable access throughout the region. Ride-share pickups are at designated outer curb zones, while rental cars and car-sharing services operate from on-airport facilities with free shuttle connections.",

        "question": "When is the cheapest time to fly from Chicago to Washington?",
        "answer": "Average fares on Chicago to Washington bottom out around $274 in late January, with the cheapest months overall being January at $282 and September at $284. The most expensive stretch is late December, when average fares climb to about $333, making December the priciest month at $324.",
        "methodology": "Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.",

        "question": "How far in advance should I book tickets from Chicago to Washington?",
        "answer": "For flights from Chicago to Washington, the optimal booking window is roughly 4-7 weeks before departure, when average fares bottom out around $223. Booking about 35 days ahead yields the single cheapest price of $222, while waiting until the last minute can push fares up to $392. Summer and holiday periods typically require booking even earlier — often 8-10 weeks out — to secure similarly low fares, as demand pushes prices higher closer to departure.",
        "methodology": "Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.",

        "answer": "Yes, a nonstop red-eye is available from Chicago to Washington. Southwest operates it from Midway (MDW) to Reagan National (DCA) on Tuesday and Wednesday nights, departing at 9:00 PM. Since this is a short flight, it lands the same night rather than the next morning.",
        "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.",

      },

        "question": "How reliable are on‑time arrivals on this route from Chicago to Washington?",
        "answer": "Southwest Airlines is the most reliable carrier on this route, with 75.2% of flights arriving within 15 minutes of schedule and a 1.3% cancellation rate. United Airlines follows at 73.2% on-time arrivals with a 0.9% cancellation rate, while American Airlines trails at 66.0% on-time arrivals and a 3.5% cancellation rate.",
        "methodology": "On-time arrival and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; a flight counts as on time when it arrives within 15 minutes of schedule.

        "question": "Which airport should I use in Washington?",
        "answer": "Washington has three airports. Reagan National is closest to downtown and the National Mall, ideal for short domestic flights. Dulles is a major international hub with more long-haul and Star Alliance flights. Baltimore/Washington is a low-cost carrier base, though farther from central Washington."
      },
      "q13": {
        "question": "How do I get to Dupage County from the city center?",
        "answer": "To reach Chicago Midway International Airport from downtown, the CTA Orange Line train is the fastest and most popular option, taking about 25 minutes. Taxis and rideshares are also convenient, with a taxi from downtown typically costing $35–40, while shared ride vans cost about $18 per person. Driving yourself is possible with on-airport hourly, daily, and economy parking lots, plus reserved parking, though it is generally more expensive than transit. Regional shuttle buses serve the airport from wider areas, but from the city center the train or a ride-hailing app is the most practical.",

Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated.
